The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

The exogenous delivery of prebiotic organic compounds to Earth likely played a role in the chemical evolution that gave rise to the origin of life. Meteorite studies have demonstrated that some of the chemical building blocks of life may have been delivered to the primordial Earth by small solar system bodies. While simple organic monomers, such as amino acids, have been heavily studied in the meteorite literature, the polymerization products of these compounds, namely peptides, have been understudied.

Exploring the peptide content of meteorites will better constrain the extent to which small solar system bodies could have delivered larger, more complex biomolecules to the early Earth. Such insights will shed new light on the possibility that meteorites may have expanded the prebiotic chemical inventory en route to the formation of primitive proteins. This NPP opportunity focuses on developing new, sensitive analytical tools to detect and quantify a wide array of abiotic peptides, which will then be used to examine the peptide chemical space in a suite of meteorites.

The implications of this research will be directly relevant to the soluble organic analyses of samples returned by space flight missions such as OSIRIS‑REx, Mars Sample Return, JAXA Hayabusa2, and MMX missions.
